This fixes a few leftovers where we use WASM_EXEC_TEST, but then
unconditionally execute the compiled code, and also changes more tests
to use WASM_EXEC_TEST, hence run in both the interpreter and compiled
code.
Once we have land the baseline compiler, those tests will also execute
in baseline compilation mode.

This required splitting wasm-run-utils.h in header and implementation,
since the anonymous namespace in wasm-run-utils.h is now gone.
This is a reasonable refactoring in itself.

In JavaScript code and stubs, JSSP mirrors the CSP but may be unaligned.
But in WASM code only CSP is used, like native code, and it must be
aligned.
Calls into WASM from JS need to carefully align the C stack
pointer (csp) and restore the previous JSSP, while calls from WASM
to JS need to compute a new JSSP and restore their CSP after the
call.
